# Capillary Rise In Tube

What happen when the capillary rise occur in a tube of insufficient length?

My teacher told me that hR = constant where h is height and R is radius of sphere of which the curved surface of meniscus firm a part.
She also told me that if h become less so R has to increase so radius of meniscus has to be large.

I didn't really get what she's meant.

If we take a capillary tube of height h and put it in water then, the tube become filled with water till height h. Now if we break a tube to make it of height less than h then will water flow out?

This is homework.
radius of meniscus has to be large.
How large can the radius become? What does that imply?
will water flow out?
Work out the first question and the answer to this becomes obvious.

I told that I didn't understand what the teacher told. Any link on web that explain it would be helpful.
This is not a homework question.

I told that's what my teacher said. If I had known the meaning I wouldn't have asked the question.
